Struct IfExpression

pub struct IfExpression {
    pub if_keyword: Token,
    pub condition: Pointer<Expression>,
    pub then_keyword: Token,
    pub if_expression: Pointer<Expression>,
    pub else_if_expressions: Pointer<Vec<ElseIfExpression>>,
    pub else_keyword: Token,
    pub else_expression: Pointer<Expression>,
}

A struct representing an elseif expression, only exists in variable declarations.

Fields

if_keyword: Token

The if keyword.

condition: Pointer<Expression>

The condition after the if keyword.

then_keyword: Token

The then keyword after the condition.

if_expression: Pointer<Expression>

The expression that this statement would resolve to if the condition evaluated to true.

else_if_expressions: Pointer<Vec<ElseIfExpression>>

All elseif expressions.

else_keyword: Token

The final part of the expression, the else keyword.

else_expression: Pointer<Expression>

The final value if all other conditions were not met.

Trait Implementations

impl Clone for IfExpression

fn clone(&self) -> IfExpression

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IfExpression

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl GetRange for IfExpression

fn get_range(&self) -> Result<Range, GetRangeError>

Get the range of the node.

impl Hash for IfExpression

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IfExpression

fn cmp(&self, other: &IfExpression) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl Parse for IfExpression

fn parse( if_keyword: Token, lexer: &mut Lexer, errors: &mut Vec<Error>, ) -> Option<Self>

Try parsing the current item, starting from the passed token.

impl PartialEq for IfExpression

fn eq(&self, other: &IfExpression) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for IfExpression

fn partial_cmp(&self, other: &IfExpression) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Print for IfExpression

fn print_final_trivia(&self) -> String

Prints only the very final trivia. Used for the default implementation of Print::print, which just joins Print::print_without_final_trivia and this function.

fn print_without_final_trivia(&self) -> String

Prints the whole token including all surrounding trivia, excluding the very last trailing trivia.

fn print(&self) -> String

Prints the whole token including all surrounding trivia.

impl TryParse for IfExpression

fn try_parse(lexer: &mut Lexer, errors: &mut Vec<Error>) -> Option<O>

Try parsing and reset the lexer’s state upon failure.

impl Eq for IfExpression

impl StructuralPartialEq for IfExpression
